Recent forecasts from multiple models converge on a daytime high of 16–17°C in Cape Town on August 31, driven by southerly winds under a building high-pressure ridge following a recent cold front. Clear to mostly sunny skies and dry air will limit daytime heating, while typical late-winter sea-surface temperatures and moderate wind speeds around 8–14 mph further cap warming potential. The narrow spread between 17°C and 18°C odds reflects minor model differences in peak afternoon temperatures, with historical August averages near 17–18°C providing context for the tight market. Updated guidance from the South African Weather Service or refined model runs in the next 48 hours could shift resolution probabilities.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=fact
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
